TO ALL WHOM IT MAY CONCERN:

Be it known that I, JOHN A. WRIGHT, of Keene, in the county of Cheshire, and State of New Hampshire, have invented certain Improvements in Mops, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which- Figure I is a perspective view of my improved mop.

Figure 2 is a horizontal longitudinal section through the centre of the same, with the handle locked in the position it occupies when the mop is ready for use.

Figure 3 is a vertical longitudinal section, representing the handle in the position it occupies when the mop-cloth is being wrung out.

Figure 4 represents an improved mop-cloth invented by me. l

My present invention relates particularly to certain improvements in mops, for which Letters Patent of the United States were granted to me on the 30th day of June, A. D. 1868. The mop, constructed as described in my said Letters Patent, answers a good purpose, but the following slight difficulty is occasionally experienced:

After the pin e, to which the lugsff'are pivoted, has been drawn up within the 'lower jaw through the slots iz', the operator, in grasping the handle, sometimes inadvertently revolves it suiiciently to bring the pin in line with the slots, when the handle is free to drop from the position where it was locked to the jaws, and the handle must again be raised and relocked thereto, before the operation of mopping can be continued.

To avoid this-difficulty is the object of my present invention, which consists in providing the lower end of the sliding and revolving handle with a single stationary projection, and a male-screw thread, which iits into a. female-screw thread, tnrnedeither'within the centre of the lower jaw only, or both the upper and lower jaw, by which construction the mop may be used without accidentally unlocking the handle from the jaws.

To enable others skilled in the art to understand and'use my invention, I will proceed to describe the manner in which I have carried itout.

- In the said drawings, A is the handle, to the upper or wooden portion, a, of which is screwed or otherwise secured the lower or metal portion, b, the transverse section of which, from 6 to 7, is iiuted, and from 7 to 8 is circular, the lower extremity of' the metal portion terminating in an enlargement or projection, c, the lower surface and ends of which are carefully rounded off, so as to present no angular` points. Immediately above this enlargement or projection c is cut a screw-thread, d.4

` B is the upper'jaw, and C the lower jaw, each of which is provided, at its centre, with a circular hole, for the reception of the portionb of the handle, which is Vthus Afree to slide and revolve therein. The opposite extremities of the lowerjaw, C, are bent or cast around at right angles, as shown, the bent portions, e e,` passing through holes in the extremities of the upper jaw, B, and being provided with screwfthreads, over which turn the nuts ff, b'y which means the ends of the mop-cloth D, after being cut out at 9, in the form shown in iig. 4, are tightened, and held firmly in place between thejaws, the bight of the cloth hanging downward.

The two inner folds of this cloth are stitched together, the rows of stitches, g g, converging from the upper edges 10 10 tothe points 11 11, at the bight, (see fig. 4.) The outer folds of the cloth are stitched to theinner folds, and to each other, to insure their being twisted with them when the cloth requires wringing. Within the hole, at the cen-tre of the lower jaw, is cut a female screw, t, for the reception of the male screw d, formed on the metal portion b, just above its projection c, by which construction the handle may be drawn up and revolved, 'in order to lock it to the lower jaw, after the mop-cloth has been inserted and secured in place by tightening the nuts ff.

After theinop' has been used, and the cloth is saturated withwater, it may be wrung out Ain an extremely convenient and readyv manner, as follows: The handle is revolved suiliciently to disengage the screw-thread d from the screw thread h in the interior of the centre of the lower jaw C, when the handle is `allowed to slide down until its projection c is brought against the bight of the inner fold of the cloth, the rows of stitches gg serving to guide the projection against the centre of the bight, thus overcoming the possibility of passing out between the side edges of the cloth, a, diiliculty incident to the ordinary mop-cloths not provided with the rows of stitches g y. By now applying u, slight pressure downward, and revolving the handle, the cloth is twisted tightly around, and the water is consequently ejected therefrom.

Proceedingfrom the upper jaw, B, and cast in the same piece therewith, are two circular bifurcations, z' z',

the tops of `which unite and form a flattened bridge-piece, 12, which is provided in the centre with a circular hole, for the reception of the sliding and revolving handle A, byvwhich construction the upper'jaw may be more conveniently gra'spedfwhen the handle is turned.

When the handle is being locked in place,'or the eloth'is being wrung out, either the handle or the upper jaw B may be turned, or both may be turned simultaneously, in a contrary direction.

Any suitable material may be employed as a mop-cloth, but when cotton-waste or other similar loose material is used, it is necessary to first attach a binding to its bight, in order that the projection c may be enable to retain hold of it while being twisted.

The above-described mop is light and durable, and'besides being convenient to handle, can be furnished at a sinall cost. i

' O'Zaz'ms. v What I claim as my invention, anddesire to secure by Letters Patent, isv A sliding and revolving handle, A, with its projection e and screw-thread d, in combination'with the jaws l B C, one or-both of which are provided with a screw-thread, 74, substantially as and for the purpose set forth.

I also claim a mop-cloth, sewedl substantially as described, to insure the projection coatching into and' retaining the cloth when itlis to be twisted forv the purpose of being wrung out. y
